Deguvest
Deguvest L is a precision soldering investment developed on a scientific basis . The total expansion of
Deguvest L is matched to the dimensional behavior shown by dental precious metal alloys during the
soldering process . Deguvest L therefore produces soldered objects with extremely high accuracy of fit .
Deguvest L has outstanding strength . The compound can be shaped well and easily cut, and has high
thermal sta bility . For this reason, Deguvest L can also be used for soldering of metal-ceramic works with
high melting alloys .

Safety information
Mixing with other liquids or materials during processing health hazards as well as impairments to the
casting quality cannot be excluded .
· This product contains quartz and cristobalite, some in the form of fine dust that may penetrate the
pulmonary alveoli . Inhalation of the dust constitutes a potential carcinogenic hazard . Ensure that an
adequate suction line/ventilation is available in the workspace and near the machines .
· Inhalation the dust of the product may trigger silicosis .
· Employers must provide Class P3 respiratory protection .
· Heating the investment compound above 200 °C will result in the formation of ammonia .
Ammonia irritates the respiratory organs .
· May cause mechanical irritation of the skin and mucosa of the eye and respiratory passages .
· Irritation and caustic reactions to the skin and mucosa must be expected on local contact .
Carry out the "coarse" removal of the casting after the casting operation under water or soak the
investment material mould .
